Now before we start showing you one of our favorite vegan casserole recipes, let’s see what a casserole actually is.

What Is A Casserole?
Casseroles are amazing dishes that are made with the magic of an oven. It truly is magic when you cut out a nice steaming slice of any kind of casserole and find all ingredients properly cooked, with all textures perfectly complementing each other. Simply put a casserole is a type of a dish that is oven baked, and has been the ultimate comfort food for winter days.
What Is The Difference Between A Stew And Casserole?
Casserole and stew differ in the way we cook them and the pot that we use for cooking them. Mainly a stew is cooked on the stove, whereas the casserole is baked in the oven. In this recipe, we combine both methods. We cook it first over the stove and then complete the cooking in the oven because anything oven-baked has more flavor.
Also, casseroles might use a lot of cheese especially on the top that wouldn’t be part of a stew dish. But with this healthy casserole recipe, we want to show that it is still possible to make scrumptious cauliflower dinner recipes without cheese.

About Making This Vegetarian Cauliflower Casserole
How do you know when a cauliflower is cooked? We get it, it can be a little tricky to tell when a cauliflower is properly cooked. Here’s a tip that can help you check whether the cauliflower is cooked before it gets too soft. Ideally, you’d want the cauliflower to be al dente. Use a fork to continue checking whether the cauliflower is just the right amount of firm that will be perfect for your vegan casserole.
To make the dish flavourful, you would need to add tomatoes, garlic, ground black pepper, chilli powder and home made tomato paste or red pepper paste (you can find at Middle East Markets). Moreover, we also recommend lemon and parsley for garnishing. While lemon is mostly for garnishing, you’ll be amazed to see what a difference it can make to the overall taste and texture of the dish.

How To Make Vegan Cauliflower Casserole
To make this vegan casserole, simply place the cauliflower florets in a pot, along with tomatoes, garlic. Add in some olive oil to bring out the flavour of the ingredients. Stir it a few times, and now add in your favourite spices, seasonings, and salt to taste.
Now squeeze some fresh lemon juice, and throw a wedge of lemon or the one you squeeze in the pot as well. This is to prevent the bad smell of cauliflower when cooking. Let the mixture cook till it is nice and almost tender, about 15 minutes.
Now transfer it into a baking pan and bake it in the oven, preheated to 375F/ 190C for 15-20 mins.
When done, sprinkle some parsley, and your delicious vegan casserole is ready.
Pro Tip: How do you prevent the bad smell of cauliflower that comes out when it is cooking? Our best solution is squeezing lemon and even throwing a slice of lemon in the pot when cooking. It completely removes that unpleasant flavor and smell.
